Test T3 Mobile

Open the device

Call device_list, then device_open with the selected host and device IDs. T3 boots the device and shows its live stream in the Device panel. Follow its returned quickStart, using the exact agentDevice.command and all targetArgs on every operation. Use device_screenshot to inspect the screen.

If T3 device tools or the selected device are unavailable, report the blocker and stop verification. Do not install or switch to another automation system.

Use an isolated backend

Reuse this task's healthy backend. Otherwise run vp run dev from the repository root, retain its terminal session, and read the actual backend port from the dev-runner output. Use the worktree's ignored .t3 state. Never run against ~/.t3/userdata. The Browser panel is not required for this workflow.

Test with meaningful project and thread data. Read the shared SQLite fixture reference only when inspecting or seeding SQLite. Stop the test server before fixture writes.

Launch T3 Code Dev

From the checkout being tested on the selected device host, run:

vp run mobile:install <ios|android> <device-id>

This installs the dev client for the checkout's native fingerprint: from the device, the local cache, or the shared cache in seconds, building once only when no machine has that fingerprint yet (5-15 minutes, logged to the file it names). The device id may be omitted when exactly one device is booted. It prints one JSON line; on failure it names the next command. Mobile verification includes that step unless the user prohibits it.

For a device you opened in an agent-device session elsewhere (a device pool, cloud, or remote host), run vp run mobile:install <ios|android> --session <s> from the directory you opened the session in. It installs the cached build into that session (--abi arm64-v8a for an ARM Android device; --metro <url> also opens it against Metro) and never builds.

Start vp run dev:client from apps/mobile, or reuse a healthy Metro belonging to this checkout. Open its printed development-client URL with AgentDevice open com.t3tools.t3code.dev <url> and all returned target arguments. The device must be able to reach both Metro and the isolated backend. Append &disableAutoLaunch=1&disableFab=1 to the development-client URL query when developer chrome would obscure screenshots or taps; the SDK 58 dev client applies these preferences before the app loads.

Pair and verify

Use the helper from the repository root, with the returned executable and target arguments stored in agent_device_command and the Bash array agent_device_target_args:

.agents/skills/test-t3-mobile/scripts/pair-client.sh \
  <server-port> <base-dir> <device-reachable-backend-origin> \
  "$agent_device_command" "${agent_device_target_args[@]}"

It issues a fresh credential and opens T3 Code Dev's existing pairing route through AgentDevice. For a backend on the device host, use http://127.0.0.1:<server-port> on iOS or http://10.0.2.2:<server-port> on Android. For a remote backend, use its reachable origin.

Confirm the intended projects appear, exercise the affected flow, and capture evidence. Retain the app and environment while iterating. At teardown, remove the disposable connection, close the AgentDevice session, call device_close, and stop only your backend and Metro processes.
